Description

Technical Field

[0001] This utility model relates to the field of C-shaped steel manufacturing technology, specifically a C-shaped steel cutting machine. Background Technology

[0002] C-shaped steel, as the name suggests, is steel with a shape resembling the capital letter "C". C-shaped steel has thin walls, light weight, excellent cross-sectional properties, and high strength. Compared with traditional channel steel, it can save 30% of material for the same strength, making it a highly efficient and economical cross-sectional profile. After C-shaped steel is processed and formed, it needs to be cut. There are various cutting equipment available, such as laser cutting equipment.

[0003] A search revealed a Chinese patent (publication number: CN212310987U) disclosing a C-shaped steel cutting device. This device includes a worktable positioned along the length of the C-shaped steel for holding it. A cutter head is positioned above the worktable, and a first motor is mounted on one side of the cutter head to drive its rotation. A protective cover is fitted over the upper outer part of the cutter head, and the cutter head and the protective cover are rotatably connected. The rotation axis of the cutter head is parallel to the length direction of the C-shaped steel. A first cylinder is positioned between the protective cover and the worktable to move the cutter head up and down. This invention allows for the cutting of C-shaped steel to the required length after processing, thus facilitating subsequent handling by workers.

[0004] The aforementioned patent uses a third cylinder to push two clamping plates closer together during operation, thereby clamping and fixing the C-shaped steel. However, the distance between the two clamping plates is limited, making it difficult to clamp and fix larger C-shaped steel, which has certain limitations. Therefore, improvements are needed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a C-shaped steel cutting machine, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A C-shaped steel cutting machine includes a cutting mechanism. The feeding end of the cutting mechanism is provided with a convex base for placing C-shaped steel, and the C-shaped steel is upside down on the convex base.

[0008] The most significant design difference of this utility model is that: sliding plates are slidably provided on the two lower surfaces of the top of the convex base, and elastic clamping columns are rotatably provided on the upper surface of the sliding plates; and a structure for facilitating the movement of C-shaped steel is provided at the highest point of the convex base, with the clamping columns clamping and fixing the C-shaped steel to the convex base.

[0009] To clamp and fix C-shaped steel of different sizes, slots are provided on both sides of the lowest point of the convex base. A rod is fixed on the side of the sliding plate near the slot. The rod is inserted into the slot and slides with the slot. An elastic element, which is a spring, is provided between the sliding plate and the lowest side of the convex base. The spring is sleeved on the rod.

[0010] To enable the movement of the C-shaped steel, the structure for facilitating the movement of the C-shaped steel includes a mounting groove formed at the highest point of the convex base, a rotating shaft rotatably disposed within the mounting groove, and the top of the inner wall of the C-shaped steel contacting the outer surface of the rotating shaft.

[0011] To collect debris, a dust collection box is detachably installed at the end of the convex base.

[0012] Compared with the prior art, this utility model has the following advantages: sliding plates are set at the two lowest points of the convex base, and then clamping columns are set on the upper surface of the sliding plates. Finally, the spring rebound force is used to push the clamping columns closer to one side of the C-shaped steel, thereby clamping and fixing the C-shaped steel. Moreover, this device can clamp and fix C-shaped steel of different sizes. It has a simple structure and is easy to operate. Attached Figure Description

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0022] like Figure 1 and Figure 4 As shown, this utility model provides a C-shaped steel cutting machine, including a cutting mechanism. The feeding end of the cutting mechanism is provided with a convex base 1 for placing C-shaped steel M. The C-shaped steel M is upside down on the convex base 1. A laser cutting machine is provided at one end of the convex base 1.

[0023] like Figure 1 As shown, the most significant design difference of this utility model is that: sliding plates 2 are slidably provided on the two lower surfaces of the top of the convex base 1, and elastic clamping columns 3 are rotatably provided on the upper surface of the sliding plates 2. The highest point of the convex base 1 is provided with a structure for easy movement of C-shaped steel M.

[0024] like Figure 4 , Figure 5 and Figure 7 As shown, in order to clamp and fix C-shaped steel M of different sizes, slots 4 are provided on both sides of the lowest point of the convex base 1. A rod 5 is fixed on the side of the sliding plate 2 near the slot 4. The rod 5 is inserted into the slot 4 and slides with the slot 4. An elastic element is provided between the sliding plate 2 and the lowest side of the convex base 1. The elastic element is a spring 8. The spring 8 is sleeved on the rod 5. The setting of the spring 8 enables the clamping column 3 to clamp and fix C-shaped steel M of different sizes.

[0025] like Figure 2-4 As shown, in order to move the C-shaped steel M, the structure for facilitating the movement of the C-shaped steel M includes a mounting groove 6 at the highest point of the convex base 1. A rotating shaft 7 is rotatably installed in the mounting groove 6. The rotating shaft 7 is cylindrical, and the top of the inner wall of the C-shaped steel M contacts the outer surface of the rotating shaft 7. The installation of the rotating shaft 7 makes it easier for the C-shaped steel M to move on the convex base 1. In addition, the rotating shaft 7 can also be a spherical steel ball, or rotating rollers can be installed at both ends of the convex base 1, with the two rotating rollers connected by a chain drive, as long as it can achieve the movement of the C-shaped steel M.

[0026] like Figure 5 As shown, in order to collect debris, a dust collection box 9 is detachably installed at the end of the convex base 1. The dust collection box 9 can be installed and removed using bolts. When the C-shaped steel M is cut, the generated debris will fall into the dust collection box 9, preventing the debris from falling directly to the ground.

[0027] The specific working principle is as follows: When in use, first pull the sliding plate 2, which will drive the insertion rod 5 to move, so that the insertion rod 5 is pulled out from the slot 4 and stretches the spring 8. When the sliding plate 2 slides on the two lowest points of the convex base 1, it will also drive the clamping column 3 to move synchronously. Then, the C-shaped steel M is inverted on the convex base 1, so that the top inside the C-shaped steel M contacts the rotating shaft 7 set at the highest point of the convex base 1. Finally, the sliding plate 2 is released, and the spring force of the spring 8 is used to drive the clamping column 3 to move closer to one side of the C-shaped steel M, thereby clamping and fixing the C-shaped steel M. Finally, the C-shaped steel M is pushed, so that the C-shaped steel M moves continuously towards the laser cutting machine set at the end of the convex base 1, thereby performing the cutting operation on the C-shaped steel M.

[0028] Compared with the prior art, this utility model has the following advantages: sliding plates 2 are set at the two lowest points of the convex base 1, and then clamping columns 3 are set on the upper surface of the sliding plates 2. Finally, the spring force of the spring 8 is used to push the clamping columns 3 closer to one side of the C-shaped steel M, thereby clamping and fixing the C-shaped steel M. In addition, the setting of the spring 8 enables the device to clamp and fix C-shaped steel M of different sizes. The structure is simple, the operation is convenient, and the application range is wider.
